I was wondering if it was possible to summon a slime that didn't hurt you. I've tried using the "NoAI:1" tag, yes, it makes it unmoving, but it still attacks if you get too close to it. This is the command I have currently:
/summon Slime ~ ~ ~ {CustomName:"BeingSlow",NoGravity:1,Invulnerable:1,Size:3,Silent:1,NoAI:1}
